Ectopic gene conversions increase the G + C content of duplicated yeast and Arabidopsis genes.

Allelic recombination has previously been shown to increase the GC-content of the sequences of a wide variety of eukaryotic species. Ectopic recombination between clustered tandemly repeated genes has also been shown to increase their GC-content. Here we show that gene conversions between the dispersed genes found in the duplicated regions of the yeast and Arabidopsis genomes also increase their GC-content when these genes are more than 88% similar.
